Description:
A “Parker Shaft Soup” mix of minerals — without the rare ones. Mostly present in this sample are margasonite, fluorescent bright light blue under shortwave UV light, axinite-Mn, fluorescent red, and willemite in green. For whatever reason, the previous owner painted his number on the margarosanite face… I guess I am missing something more interesting on the other faces!
